<p><span style="font-size: medium">第二分钟，L说，要能修改，于是便有了将左上角为(a,b)，右下角为(c,d)的一个矩形区域内的全部数字加上一个值的操作。</span></p>
<p><span style="font-size: medium">第三分钟，k说，要能查询，于是便有了求给定矩形区域内的全部数字和的操作。</span></p>
<p><span style="font-size: medium">第四分钟，彩虹喵说，要基于二叉树的数据结构，于是便有了数据范围。</span></p>
<p><span style="font-size: medium">第五分钟，和雪说，要有耐心，于是便有了时间限制。</span></p>
<p><span style="font-size: medium">第六分钟，吃钢琴男说，要省点事，于是便有了保证运算过程中及最终结果均不超过32位有符号整数类型的表示范围的限制。</span></p>
